YC1 gene

摘要

Isolated and purified YC1 genes and proteins are disclosed. The protein binds to a site in the HIV-LTR, the NRE-1 site, and can inhibit the expression of a gene operably linked to the HIV-1 LTR. The use of the protein and gene are discussed. Repressible and inducible expression systems using the YC1 gene are also disclosed.
